Description
Metal-organic frameworks (MOFs) are a subclass of coordination polymers (CPs), distinguished by porosity, applicable in many areas of industry, such as catalysis, gas storage and separation, energy storage or drug delivery. MOFs crystallize in various forms, derived from the structure of the unit cell, internal forces within the structure and other factors.
MOFs can form single crystals as well as more complicated structures, containing multiple single crystals oriented towards one another in a specific way, forming superstructures. Those aggregates can have one- or three-dimensional orientation, influencing some properties of the material, which allows their modification by forming superstructures. One of the 3D-oriented crystals are radially oriented crystallite rods, called spherulites. Those forms can be recognized by a distinctive Maltese cross when observed under polarized light.
Spherulites are mainly formed by polymers, but recently formation of these superstructures was observed in MOF-74. In this talk, a novel isoreticular MOF-74 material forming spherulite superstructures and its potential functionalization by post-synthetic modifications will be presented.
